如何从字典向python中的json文件添加字符串

import json

with open("file.json", "a") as json_file:
    # 执行后续操作

with open("file.json", "a") as json_file:
    data = json.load(json_file)

data["key"] = "value"

with open("file.json", "w") as json_file:
    json.dump(data, json_file)

import json

# 打开JSON文件并读取内容
with open("file.json", "a") as json_file:
    data = json.load(json_file)

# 添加字符串到字典
data["key"] = "value"

# 写入更新后的字典到JSON文件
with open("file.json", "w") as json_file:
    json.dump(data, json_file)
